My TRAPPIST-1 texture designs are based on Io, Mars, Enceladus, Europa and Earth textures. The main problem is in my opinion to imagine a "real" exoplanet...There are a lot of known unknowns and a lot of unknown unknowns.

The 8k textures are too big to upload (the add-on is currently larger than 500 MB - with clouds), but here are the actual versions in Celestia:

I'm newbie, I just signed up for this forum last week.I was planning on showing you guys my textures, but john71, your textures are flat out the best ever made.John Van Vliet's are great too, and he's a great and pure artist, but there's no comparison.

Since they're too big for you to upload, maybe because the computer isn't powerful enough or maybe you could reduce the texture sizes to 4k(4096x2048) or maybe the biggest you could probably upload is 6k (6144x3072)

Still, your work is outstanding and makes so much sense, I do believe the Neptune-like impression on TRAPPIST-1 g for NASA is due to a large greenhouse effect and lots of clouds and weather, but you do good with yours, maybe add a moderate pinch effect towards the starlit side, it's like MiR's 51 Pegasi texture, but to a lesser extent.The clouds would look kinda fuzzy and mid-tone, and not completely opaque (there would be breaks in areas), but still, your work is amazing and phenomenal.

It takes imagination to make them how you want them, and you guys, and I, have excellent imagination.

john71, These textures are great, I can't even make TRAPPIST-1 textures that good, no matter what they're based on, I would try my best, You are a true artist.I always felt they make the most sense to have in Celestia, which I use since 2011, and what they might look like up close.To upload the textures, their sizes may need to be reduced to either 6k or 4k, but again, excellent work.This add-on needs to be on the Motherlode, which I go on, Users would LOVE it!A+

john71, Well congratulations to Tim Pyle and Robert Hurt, but also congrats to you for your tries and imagination.You really do good at art and imagination, but so do they, but again, I would like to see how they turn out, but then again, being to big for upload at 8k, might need reducing to 6k or 4k (as that is usually how large fictional exoplanet textures get).

john71, Take your time, I love the results, keep up the good work, and again, your impression's getting an A+ and when I saw first saw these textures, I thought they were satisfying, and they are great, again keep up the great work.
